Submerged arc welding (SAW), joalo ka ha lebitso le bontša, e etsoa ka tlas'a lera le sireletsang kapa kobo ea flux.Ha arc e lula e koahetsoe ke botenya ba flux, e felisa mahlaseli leha e le afe a tsoang ho li-arches tse pepenene le tlhokahalo ea li-skrini tsa welding.Ka mefuta e 'meli ea ts'ebetso, e ikemetseng le ea semi-automatic, ke e' ngoe ea mekhoa e sebelisoang haholo ea ho tjheseletsa e sebelisoang indastering ea ts'ebetso.Wenzhou Tianyu Electronic Co., Ltd., e leng e mong oa barekisi ba tummeng ba terata ea arc e ka tlas'a metsi naheng ea China, e bonts'a molao-motheo le ts'ebeliso ea li-welding tsa sub-arc.A re boneng hore na ke eng:
Tshebetso:
Akin to MIG welding, SAW e boetse e sebelisa mokhoa oa ho theha arc pakeng tsa motsoako oa weld le terata e sa khaotseng ea electrode.Lera le tšesaane la flux le slag li sebelisoa ho hlahisa metsoako ea khase e sireletsang le ho eketsa li-alloys tse hlokahalang letamong la weld, ka ho latellana.Ha weld e ntse e tsoela pele, terata ea elektrode e lokolloa ka lebelo le ts'oanang la ts'ebeliso mme phallo e feteletseng e ntšoa ka sistimi ea vacuum bakeng sa ho sebelisoa hape.Ntle le ho sireletsa mahlaseli a kotsi, likarolo tsa flux le tsona li molemo haholo ho qoba tahlehelo ea mocheso.Ts'ebetso e ntle ea mocheso oa ts'ebetso ena, hoo e ka bang 60%, e hlahisoa ke likarolo tsena tsa flux.Hape, ts'ebetso ea SAW ha e na ho fafatsa 'me ha e hloke ts'ebetso ea ho ntša mosi.
Mokhoa oa ho sebetsa:
Joalo ka ts'ebetso efe kapa efe e meng ea tjheseletsa, boleng ba manonyeletso a mabapi le botebo ba ho kenella, sebopeho le sebopeho sa lik'hemik'hale tsa tšepe ea weld e kentsoeng hangata li laoloa ke liparamente tsa welding joalo ka hajoale, voltage ea arc, sekhahla sa phepelo ea terata ea weld, le lebelo la ho tsamaea.E 'ngoe ea litšitiso (ehlile mekhoa e teng ho li hanyetsa) ke hore welder e ke ke ea shebana le letamo la weld mme ka hona boleng ba seliba bo itšetlehile ka ho felletseng ho li-parameter tsa ts'ebetso.
Mekhoa ea ts'ebetso:
Joalokaha ho boletsoe pejana, ke feela ka mekhahlelo ea ts'ebetso, 'me welder o phethahatsa motsoako oa weld.Mohlala, ts'ebetsong ea boiketsetso, boholo ba terata le phallo e sebetsang tse loketseng mofuta o tloaelehileng, botenya ba thepa le boholo ba mosebetsi li phetha karolo ea bohlokoa ho etsa qeto ea sekhahla sa deposition le libopeho tsa lifaha.
Mohala:

Flux:
Motsoako oa granular oa li-oxide tsa likarolo tse 'maloa tse kang manganese, titanium, calcium, magnesium, silicon, aluminium, le calcium fluoride e sebelisoa haholo e le phallo ho SAW.Hangata, motsoako o khethoa e le hore o fane ka thepa ea mechine e reretsoeng ha e kopanya le terata ea welding.Hape hoa lokela ho hlokomeloa hore ho hlophisoa ha li-fluxes tsena ho phetha karolo ea bohlokoa ho li-voltage tsa arc tse sebetsang le li-parameter tsa hona joale.Ho ipapisitsoe le tlhokahalo ea welding, haholo-holo mefuta e 'meli ea fluxes, e kopantsoeng le e kopantsoeng e sebelisoa ts'ebetsong.
Lisebelisoa:
Mokhoa o mong le o mong oa tjheseletsa o na le lisebelisoa tsa ona, tseo hangata li kopanang ka lebaka la boholo ba moruo le tlhokahalo ea boleng.
Leha SAW e ka sebelisoa hantle bakeng sa manonyeletso ka bobeli a butt (longitudinal le circumferential) le manonyeletso a fillet, e na le lithibelo tse nyane tse fokolang.Ka lebaka la ho phalla ha letamo la weld, slag sebakeng se entsoeng ka ho qhibiliha le lesela le hlephileng la phallo, manonyeletso a butt a lula a etsoa sebakeng se bataletseng, 'me ka lehlakoreng le leng, manonyeletso a fillet a etsoa maemong ohle - a bataletseng, a otlolohileng, le tse otlolohileng.
Hoa lokela ho hlokomeloa hore hafeela mekhoa e nepahetseng le khetho ea litekanyetso tsa litokisetso tse kopanetsoeng li etsoa, SAW e ka etsoa ka katleho bakeng sa thepa ea botenya leha e le bofe.
E ka sebelisoa hantle bakeng sa litšepe tsa k'habone, litšepe tse sa hloekang le litšepe tse tlase tsa alloy hammoho le lisebelisoa tse seng kae tse se nang ferrous, ha feela ho sebelisoa khoutu ea ASME e khothalelitsoeng ho kopanya terata le flux.
SAW e fumana sebaka sa ka ho sa feleng indastering ea mechine e boima le indastering ea kaho ea likepe bakeng sa likarolo tse ngata tsa welding, liphaephe tse kholo tsa bophara le likepe tsa tšebetso.
Ka tšebeliso e phahameng haholo ea terata ea elektrode le menyetla e fumanehang ea ho iketsetsa, SAW e lula e le e 'ngoe ea mekhoa e batloang ka ho fetesisa ea ho cheselletsa indastering ea tlhahiso.
